Applications

SMS reporting directly to your mobile phone.
The SMS reporting option for the CellVoice 4 RTU allows you to report alarms via SMS directly to your phone.


Wireless reporting to the NOC in a single step.
You can also report alarms wirelessly via CDMA/GSM directly to your alarm management system with the SMS Receiver. The SMS Receiver forwards incoming SMS alarm messages as SNMP traps to your alarm master. This saves you the trouble of paying for a third party cellular data provider. You also won't be punching a hole in your firewall to receive alarms from your cellular devices.
